Youtube playlists filled with child-friendly videos AND hardcore porn are putting kids at risk of seeing XXX clips online, The Sun can reveal.

Pervy YouTube users are creating twisted playlists that start off with videos of colouring, cartoons and video games – but quickly descend into hardcore pornography.

A spokesperson from the NSPCC slammed YouTube over the fiasco, saying it risks giving children “a distorted view of sex, body image and healthy relationships”.

Last week, we revealed that YouTube was hosting XXX videos that had racked up millions of views.

But some sickos are taking advantage of the YouTube’s inability to keep smut off the video-sharing site.

The Sun found at least nine different YouTube porn playlists that began with child-friendly videos.

One playlist began with several clips about colouring in pictures, and eventually led to a video of an oral sex scene culminating in a man ejaculating on a woman’s face – with genitals in full view.

Several other videos including explicit sex scenes, including clear footage of vaginas, breasts and penises.

One particularly twisted clip featured women locked in cages and forced to have oral and vaginal sex with men.

In some scenes, the women were held at gunpoint during intercourse, and were even being whipped.

Women in the clip were physically injured and several graphic scenes involved blood.

Google-owned YouTube’s nudity and sexual content policy clearly prohibits this sort of content from being uploaded.

“YouTube is not for pornography or sexually explicit content,” the tech giant explains.

“If this describes your video, even if it’s a video of yourself, don’t post it on YouTube.

“If a video is intended to be sexually provocative, it is less likely to be acceptable for YouTube.

“Sexually explicit content like pornography is not allowed.”

But the pornographic videos seen by The Sun were clearly intended to be erotic, and should not be seen by children.

An anonymous Sun reader told us how they had been aware of these playlists for at least a year.

“These sick people are using thumbnails for videos that are being directed towards luring kids to watch their videos,” the concerned YouTube user told The Sun.

“Then the playlist loads porn videos – so they watch a few kids vids and then the porn movie loads.”

The situation for children on YouTube is worrying.

Some adult-themed videos are placed behind an 18+ age restriction block.

But YouTube doesn’t actually check to make sure that users who say they’re older than 18 actually that age.

That means children can sign up to YouTube with a fake date of birth and access any video – including hardcore porn that’s made it through YouTube’s checks.

Speaking to The Sun, an NSPCC spokesperson said: “Pornography gives children a distorted view of sex, body image and healthy relationships and in our research we found that nearly half of children who’ve seen pornography first stumbled on it by accident.

“These videos, apparently hidden in seemingly child-friendly playlists, are a clear example of YouTube breaching its own guidelines.

“Social networks and sites must prioritise child protection and we need the Government to step in and end the Wild West of the Web.

“That includes a requirement for automatic safe accounts for under 18s, that should protect them from pornographic and inappropriate content.”

According to a recent NSPCC report, 46% of children who’ve seen porn first saw it by accident.

And nearly two-thirds of 15-16-year-olds have seen pornography.

When asked for comment, a YouTube spokesperson said they would “look into it”.

Earlier this month, The Sun made YouTube aware of explicit porn playlists containing dozens of videos.

After we exposed the shocking clips, YouTube took down a number of the offending videos.

In a statement given at the time, a YouTube spokesperson said: “We do not allow pornography on YouTube.

“We do allow videos with artistic or educational value but we apply an age restriction where appropriate.”

Our report following another Sun revelation that YouTube was showing pornographic ads on some videos.

The raunchy advertisements directed users to webcam sex sites where punters pay for XXX performances live on camera.

Following that article, a YouTube spokesperson told The Sun: “We have clear policies against ads featuring graphic adult content.

“When we become aware of an ad that violates our policies, we immediately remove it and take appropriate action, including, and up to, suspending the responsible account.”

And in March, a separate The Sun Tech report revealed how YouTube was pushing a rogue ad asking users to “order steroids”.

Anabolic steroids are a dangerous way to build muscle mass very quickly, and are controlled as Class C substances under the Misuse of Drugs Act 1971 in the UK.

One concerned parent told us his kids had to watch the full 49-second steroids ad – which promised “fast results” with “no side effects” – before being able to see a video of kittens.

We also recently revealed how YouTube’s special app for children had video guides on how to make an air rifle.
